HAND-TOOL.

ma am.

To all whom it may concern:

, Be it known that I, VALDEMAR F. REIcH, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Tmprovementsin Hand-Tools, of which mprovements the following is a spec1ficat1on.

My invention relates to tool holders, such as glass cutters, the heads of which are provided with means for detachably connecting rotary tools to them, and the object thereof is to provide a tool holder of simple construction in which onerotary tool may be quickly substituted for another, and 1n which the tool, when it is locked in operative position, may not be accidentally re leased. A further object is to provide the handle of a tool holder of the general character described with a simple, practical and convenient magazine for carrying a plurality of tools.

While my invention may be used for tools for various purposes, it is particularly applicable to glass cutters, and is so illustrated in the accompanying sheet of drawings which form part of my specification.

Figure 1 of the drawings is a combined side and sectional view of the tool holder, the sectional portion of the view being takenon the line TT, Fig. 2; Fig. 2 a combined section and plan view, the plane of view being taken on the broken line 11-11, Fig. 1; Fig. 3 a view to enlarged scale of the right-hand end of the tool holder; Fig. i

i a side view of a modifiedform of tool carrier; Fig. 5 a vertical sectional view of a modification of construction; Fig. 6 a side view of an alternate form of tool; Fig. 7 a sectional View taken on the line VIIVII, Fig. 1; and Fig. 8 a view similar to Fig. 1 showing the tool carrier and magazine in outward positions.

The tool holder which I provide includes a handle 1 and a head 2, preferably formed of a single piece of metal. Between the handle and head there may be formed a flattened portion 3, the faces of which are roughened so that the tool may be held firmly between the thumb and'first finger when the handle of the'tool projects between the first and second fingers. To the end that, when operating the tool in such position in the right hand, the head may lie 1n a plane perpendicular to the glass being cut or other article being operated upon, the

head is bent laterally from the longitudinal axis ofthe handle, as indicated in Fig. 2.

In the preferred embodiment of my invention, as far as such invention concerns the construction of the head of the tool, the head is provided interiorly with a longitudinally extending groove 4, open at its outer end to receive the tool carrier. The wall surrounding such groove is provided at the inner end of the groove with a lateral opening 5 which may be either in the side of the head, as shown in' Fig. 2, or in the top, as indicated. in Fig. 5. Within the groove 4 there is arranged a tool carrier 6 longitudinally slidable from the position indicated in Fig. 8, in which the tool may be readily placed in or removed from the carrier, to the position indicated in Figs. 1 and 2, in which the tool is held in operative position. The carrier 6 is preferably bifurcated at its outer end, and is provided on its top with grooves 7 adapted to receive the axle 8 of the rotary tool 9, such as the glass-cutting wheel. When the carrier is in the .positionindicated in Fig. 1 the axle 8 of the tool 9 is held in the grooves 7 by the flanges 20, Fig. 3. To hold the carrier lock in its inner or operative position the carrier is preferably provided with a spring arm 10, on the outer end of which there is formed a 'detent 11 adapted to snap into outwardlyuntil the bearing grooves 7 of the carrier are in the exposed position indicated in Fig. 8, in which the wheel or tool may be readily removed. The carrier may then be moved inwardly to the position iii-e100 dicated in Figs. 1 and 2, in which the detent again snaps into the opening 5.

In Fig. 4 there is illustrated an alternate form of carrier, the inner end of which is bifurcated and provided witha series of 105 slots 12 to receive a plurality of rotary, tools 13. By so constructing the ,carrier, it maybe used as a magazine for carrying substitute rotary tools The carrier being readily slidable the full length of the groove 110 in the head, it may be withdrawn at any time a sufficient distance to remove any one tools.

of the substitute tools 13 and place it in the bearing 7 at the outer end of the carrier.

As already stated, my invention contemplates the provision of a tool-carrying magazine in the handle of the tool holder. To such end the handle is provided with a longitudinal bore 14 adapted to receive a longitudinally slidable magazine 15, which,

as shown herein, may be bifurcated to re-' ceive a plurality of cutting disks or other To the outer end of the handle there is rotatably attached a cap 16 having screw thread engagement with the outerend of the handle. 7

When it is desired to remove a disk from the magazine 14, the cap 16 may be un screwed, the magazine 15 being held against turning with the cap by means of the angu lar form of the magazine and bore 14, and, after the cap has been disengaged from the screw threads of the handle, the magazine may be pulled outwardly to an extent desired for the removal of a'tool, as is indicated in Fig. 8.., After the removal of a tool the magazine may be moved inwardly and the cap quickly screwed upon the head of the handle 1.

My invention, whileparticularly applicable to glass cutters, may be used for other ournaled in said bearings, said carrier being slidable in said groove from an inward position in which the walls of said head surrounding the carrier hold said tool in its bearing to an outward position in which said tool may be freely removed from its bearings, and means for locking said carrier in its inward position. 1

2. In a hand ,tool,-the combination of an elongated body including a head and handle,

said head being provided 'interiorly with a groove open at the outer end of the head, the wall surrounding said groove being provided with a lateral opening at the inner end of the groove, and a tool carrier longitudinally slidable in said groove and provided at its outer end with means to re ceive a tool freely removable from the carrier when it is in its outward position, said carrier being provided with a spring;arm having a detent which when the carrier is in its inner end snaps into said lateral opening to lock the carrier.

3. In a hand tool, the combination of an elongated body including a head and handle,

said head being provided interiorly with a groove disposed longitudinally of the head and open at the outer end of the head, the wall surrounding said groove being provided with a lateral opening at the inner end of the groove, a tool carrier longitudinally slidable'in said groove and bifurcated at its] outer end to receive and form bearings for a rotary tool, a rotary tool journaled in said bearings, said carrier being slidable in said groove from an inward position in which the walls of said head surrounding the carrier hold said tool in its when the carrier is in its inner end snaps intov said lateral opening to lock the carrier. 4. In a hand tool, the combination of an elongated bodyincluding a head and handle, said head being provided with means for removably attaching a tool to it, said handle being provided with a longitudinal bore open at the outer end of the handle, a tool magazine longitudinally slidable but non rotatable in said bore, and a cap rotatably mounted on the outer end of said magazine,

said cap having screw thread engagement with the outer end of said handle.

In testimony whereof I have hereunto set my hand.
